To all 'whom it may concern:

Be it known that I, JOHN AO. Nnn'gnzx, a citizen of the United States, residing at Morgan Park, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Ballast- Cars, of which the following is a description, reference being had to the accompany` ing drawings, which form a part of myspecification. t

My invention relates to animprovement in ballast cars, having to do more especially with the underframe of a ballast car knownmore clearly illustrate my invention'. Fig.

, 3 is a transverse sectional view taken on the line c a of Fig. 2 looking in the direction of the arrows. Fig. 4 is a detailed view in perspective of the underframe of the car.

My invention has to do with the construc tion of the steel underframe of a ballast car and more especially of the Hart convertible type of ballast car as illustrated in the drawings.

As the invention merely relates to the construction of the undeiframe, the description will be confined to that portion of the car.

In a ballast car of the type referred to and illustrated in the drawings, no longitudinal sillis employed as such a sill wouldl obstruct the flow of material through the hopper. The load carrying members of the car comprise two intermediate, longitudinal sills 1 1, which extend longitudinally of the car adjacent to the hopper 2 2, as can be more clearly seenin Fig. 3, and outside longitudinal or side sills 3 3; all of the Vlongitudinal sills being connected together are formed as girders, which may be of any suitable construction. As shown, they are formed as plate girders comprising web portlon 5 for the intermediate sills and angle irons 6 and 7 riveted to the upper and lower edges of the web portion respectively. The side girders are similarly formed with web portion 8 to which angle -irons 9 and 10 are riveted at the uppei' and lower edges res ectively.

s a considerable portion of the load will be carried by the intermediate longitudinal sills 1 1, these sills are preferably made of greater depth than the side sills 3. A portion of the strains on the intermediate longitudinal sills is transmitted to the side sills 3. In order to provide for the effective transmission of strains from the intermediate sills to the side sills, I provide webs 5 of the intermediate sills with openings, or passages, there-lV through.

The'transverse sills or cross members 11 may be in the shape of a channel iron as illustrated, see F igs.l 1 and 4, or of any suitable shape having the requisite strength.

Where the intermediate sills are constructed as illustrated in the drawings, the openings in the webs 5 are preferably made a short distance below the top of the web so as not to interfere with the angle irons 6 6, which constitute the horizontal flange at the upper edge of the intermediate longitudinal sill.'

The transverse member 11 after being put into position throughrthe openings in the intermediate sills is secured to both inter mediate sills and the side sills by the angle irons 12, which are securely riveted to the longitudinal sills and to the transverse sills as clearly illustrated in Figs. 3 and 4. It is apparent that when the intermediate sillsy are 'defiected the excess load will be transmitted directly through the continuous cross members to the side sills 3.

I have shown and described one method of employing my invention, but I do not wish to be understood as limiting myself to the exact construction shown, but

What I claim and wish to Secure by TItters Patent is:

In a car under-frame structure, the combination with side sills made up of vertical web plates and top and bottom reinforcing ported by the projected ends of said cro angles, of vertical joint angles riveted to the ties.

said web plates, metallic cross ties riveted J. O. NEIKIRK. to said joint angles, and having continuous Witnesses: end portions that project through the said G. F. MCHUGH,

web plates, and supplemental side sills sup- M.. E. STRUTENBURGH.
